    teplomer The temperature in Roxville decreased 15 degree in five hours. What was the average decrease in temperature per hour? Write you answer as an integer.
  • Heat transfer
    sphere_Nickel We placed a lead object weighing 0.4 kg and 250°C in 0.4 L water. What was the initial temperature of water t2 if the object's temperature and the water after reaching equilibrium was 35°C? We assume that the heat exchange occurred only between the lead o
  • Petra
    watermixing Petra likes to bathe in a bathtub with a water temperature of 38 degrees. She turned on the hot water set at 70 degrees and left for a moment. Before she returned, 40 liters of water flowed into the tub. How much water with a temperature of 22 degrees mus
  • At noon 2
    teplomer At noon, the temperature was 4 degrees fahrenheit. At 6pm, it was 10 degrees colder. What was the temperature at 6pm?
  • The aluminum
    sphere_Nickel The aluminum object with a weight of 0.80 kg and a temperature of 250°C was placed in the water with a weight of 1.6 kg and a temperature of 23°C. What is the system temperature after reaching equilibrium? We assume that the heat exchange occurred only be
  • The bath
    watermixing The bath has water with a volume of 220 l and a temperature of 65°C. Determine the mass m2 of water at 15°C to be poured so that the resulting temperature of the water in the bath is 40°C. We neglect the heat exchange between water and the environment. T
  • If the 3
    teplomer If the temperature of a city drops 2° everyday and increases by 3° on every 5 days, how long does it take to drop to -15° from temperature +5°?
  • Ground level
    teplomer The temperature at ground level in Helsinki is 20°C lower than in London. The temperature in a basement flat in Helsinki is 5°C below the temperature at ground level. If it is -29°c in the basement, what is the temperature in London?
  • At midmorning
    teplomer The temperature at midmorning was 31°C. Early in the evening, the temperature dropped by 5°C. What was the resulting temperature?
